Giant Water Spider
Megadolomedes australianus
"Megadolomedes" is a genus of spider in the family Pisauridae. It is one of Australia's largest spiders, with a legspan of up to 18 cm. Found near creeks and ponds, it is capable of running on water. Food includes small fish, tadpoles and aquatic insects. Air is trapped on body and leg hair, allowing them to stay underwater for long periods of time.
